Abstract

We propose a dual-frequency signal generation scheme based on a thin-film lithium niobate chip. The chip integrates a 1×2 Multimode Interferometer (MMI) coupler, two Phase Modulators (PMs), and two microring resonators (MRRs). By utilizing the on-chip PMs and MRRs, two Optoelectronic Oscillator (OEO) loops are constructed, enabling the generation of two distinct frequency signals. In a proof-of-concept experiment, two signals with frequencies of 13.52 GHz and 16.15 GHz are generated. The phase noise measured at a 10 kHz frequency offset is -72 dBc/Hz and -67 dBc/Hz for the two signals, respectively.
